Question

We are always told that we should clean our teeth regularly to keep them healthy and to have fresh breath. It is believed that people started using a kind of paste to clean their teeth around 5000 years ago. However, the ingredients of these tooth powders were very different from ours. For example, the people of ancient Egypt used salt, mint, dried flowers and pepper to create tooth powder. Later, in the 18th century, in some countries in Europe, people brushed their teeth with burnt bread. The first toothpaste appeared in 1890, in Great Britain. At first it was sold in jars. Then special tubes were designed to make the toothpaste more comfortable to use. 1. What should we do every day to keep our teeth healthy? 2. Who used salt, mint, dried flowers and pepper to create tooth powder? 3. When and where did the first toothpaste appear?
